Representatives for both parties haven't commented, but a source said that Depp and Heard hinted at the possibility that the relationship was on again. "Johnny and Amber were really touchy-feely when they arrived in a limo," the source said. "They spent the night hand-in-hand and Johnny was really keen to introduce her to his mates."

Depp met Heard when the two filmed "The Rum Diary" back in 2011, a few months after Depp split from his partner of 14 years, Vanessa Paradis. Depp was apparently serious about his relationship with Heard, as he built a "Rum Diary" replica bar at his Bahamas home, and bought Heard a pony. Heard, who was bisexual, allegedly left the 49-year-old actor last February for a French model Marie de Villepin.

From his former relationship with Paradis, Depp has two children, 13-year-old Lily-Rose Melody Depp and 10-year-old John "Jack" Christopher Depp III.
